One of the main concerns in the world today is depletion of energy. As citizens we must make a concerted effort to be conscious citizens and save electricity. Electricity has become integral to life but imagine having to live without power.

Conservation of electricity benefits you personally and you will pay lower bills. Note:

1. doing an energy audit. This will tell you how and when to use energy and where the waste. You can do an “energy savings plan” to indicate exactly how you can cut energy consumption. Some ideas may be as simple as not to leave the coffee machine in all the time.

At least three major cellular operators in this country who have been aiming for long term evolution network. A large-capacity networks, and high-speed radio network became the forerunner to the fourth generation or 4G.

In addition to Telkomsel, Indosat least XL Axiata and has also made preparations to move into that direction. It was not revolutionarily, but they can do to increase network capacity evolution that they have today.

This evolution is interesting because not only can be done on a GSM network, but also on the CDMA network which had been impressed by how the two different camps. Indeed, to go to Long Term Evolution (LTE), not just the infrastructure that must be perfected, but also the readiness of the terminal or mobile device that will use it.

Although too large pedestal on LTE can reduce the comfort of the wearer, the hope of cellular networks with LTE becomes very large. Especially considering competing broadband technologies, namely WiMAX, still hobbled its implementation and WiFi are less developed.

Currently many applications that can not be heavy or difficult to run through the cellular network. Call it like streaming HD video, online games, upload photos and video with high speed will also reduce the density in the base transceiver station (BTS) and spawned many new solutions.

Evolutive also taken steps to realize Indosat DC-HSPA + network first before stepping into LTE. Especially considering the speed of a DC-HSPA + network that reached 42 megabits per second (Mbps) of this there has been no device that can take full advantage.

“Through this network modernization, we also support the creation of green telco because it can reduce electric power consumption and more environmentally friendly. This would also create efficiencies for the company, “said Harry Sasongko, President & CEO of Indosat in the event that a product launch last week.

Internet access DC-HSPA + 42 Mbps since last week initially serve a new area of Central Jakarta, this implementation is claimed to be the first in Asia and second in the world. This network is an improved version of the HSPA + network downlink speed up to 21 Mbps and 5.8 Mbps uplink speeds.

High speed

Indosat to see modernization of this network has many advantages, especially in the form of operational cost efficiency saving of electric power consumption up to 50 percent efficiency and space requirements up to 67 percent. This is one effort to support creation of green telco telecom industry, apart from the use of alternative energy in the BTS.

Agreement with Ericsson last week that includes a variety of advanced technologies, such as multi-radio devices with the ability of a radio standard that allows one cabinet radio base station for transmitting signals multiteknologi (GSM, WCDMA, LTE). Evolutive steps will also make it easy to later realize its LTE service.

“To step into the LTE, the first must upgrade to LTE, core network ready (full IP network) starting from the side until the backbone. Second, upgrade the level of access networks at the base station which is currently based software (software defined radio) flexibility to upgrade its technology evolution from GPRS, EDGE, 3G HSDPA, HSUPA, HSPA, HSPA + Release 7, 8 .. until then to LTE , “said Teguh Prasetya, Group Head of VAS Marketing Indosat.

Regarding the allocation of frequencies, Teguh recommend doing refarming (reusing) the allocation to the already existing operators so that it can be very helpful, for example in the frequency band 900, 1800, or 2100 MHz. “With refarming, the risk had to do remodeling of the existing player,” said Teguh.

To be fair, this 3.9G network deployment does require 20 MHz wide frequency band. However, interestingly, this technology can flexibly sliced to 1.4 MHz. This was very different from the 3G or CDMA2000, which requires the use of 5 MHz frequency band.

In addition to the frequency spectrum efficiency, also the latency (the interval that occurs because the electronic components), a low main attraction. The average downlink speeds of 100 Mbps for mobile and 1 Gbps for nomadic, at least 50 Mbps uplink. Nevertheless, based on IMT-Advanced requirements, this has yet to be categorized as a 4G, perhaps perfected later on LTE Advanced.
